function [ similarity ] = f_CS_4_Matching_ShapeTree( feature1, feature2 )
%f_CS_4_Matching_ShapeTree: this function is used to calculate the 
%                                similarity between two features.
%   input: 
%         feature1: feature of the first object
%         feature2: feature of the second object
%   output:
%          similarity: similarity between two contour segments
